MINE-CAR WHEEL AND MEANS FOR ATTACHING SAME.

Specification of Letters Patent.

Patented Feb. flfifll itd.

Application flied July 11, 1917. Serial No. 179,874i.

To all whom it may concern Be it known that I, WARREN V. Jonnson, residing at Bloomsburg, Columbia county, State of Pennsylvania, and being a citizen of the United States, have invented certain new and useful Improvements in Mine-Car Wheels and Means for Attaching Same, of which th following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate thepreferred form of the invention, though it is tobe understood that the invention is not limited to the exact details of construction shown and described, asit is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is an end elevational view of my improved wheel;

Fig. 2 is a vertical longitudinal view taken centrally through the wheel and showing the axle in elevation; and

Fig. 3 is a fragmentary vertical sectional view, substantially as in Fig. 2, illustrating a slightly modified form of construction.

An object of the invention is to provide in a roller bearing wheel, a simple and economical construction which will permit the use of roller bearings of various typcs,wh 1ch roller bearings are properly positioned within the roller bearing chamber witlun the hub 35 washer which has been heretofore commonly of the wheel and are held in position by a employed in connection with the linch pin passing through the axle, and which washer is by me employed to hold the roller bearing assembly in position and to prevent the linch pin coming into contact with the roller hearing assembly carried within the wheel hub.

Another feature is an adjustable lubricant cup which is movable longitudinally of the axle, is adapted to contain a quantity of lubricant which, may be forced into the Wheel while seating the said cup and which cup may. be locked in position by means projecting through the wheel hub and bearing upon an inwardly extending flange of said cup.

Referring to the parts, 1 is a pedestal box of ordinary construction comprising an elongated bearing 2 from which radiates the web 3, integral with which is formed a perimetrioal flange 4 and inturned flanged portion 5, the parts 3, 4 and 5 coiiperating toholdwithin them a packing 6 of hair, felt or other suitable material, and it is to be noted that the web is undercut at 7 to serve as a seat for said packing. In position, as for use upon the axle 8, next outwardly of the pedestal box is a metal Washer 9 interposed between the pedestal box and the wheel hub 10, which latter is formed with axle bores of a plurality of diameters, the bore within which is shown a roller bearing assembly comprising the cylinder 16, which is shown as provided with integral end flanges 17 and position annuli 19 which coiiperate with the spindles of the rollers 20 to hold said rollers -1n position. In Fig. 3 the flange. 18 is omitted and the annular ring 19 may be used without said flanges.

Progressing outwardly toward the outer face of the wheel and nextbeyond the roller bearing chamber, is a lubricant chamber 21 which is of larger diameter than said roller hub, is the roller bearing chamber 15 in '18, which flangesarc adapted to hold in V bearing chamber, whereby a shoulder 22 isformed thereby providing a seat for the metal washer 23, which is of larger diameter than saidroller bearing chamber, and when held in position, as hereinafter described,

serves as a means for retaining the rollers,-

bearing assembly in position within the wheel hub. Seated within the lubricant chamber 21 is an adjustable screw-threaded flanged cup 24 provided on its outer face with projections 25 which form, with the end wall 26, a socket in which a bar or other convenient means may be inserted to rotate said cup andethereby screw the same in position within said lubricant chamber tocause the inwardly disposed flange 27 of said cup to bear upon the washer '23, thereby holding said washer in position and in turn lockin the roller bearing assembly within them ler bearing chamber of the wheel. The annular flange 29 forming the outer end of the wheel hub is perforated, screwthreaded and in service is filled by a plug 30 which" contactsigwithfithe inwardly disposed flange 27 of said lubricant cup and cooperates with the flange 27 of said cup to lock the cup in position within the wheel. Within the lubricant chamber 21, the axle is penetrated by a linch pin 32 which projects at each end through said axle into said lubricant chamber and serves as an agitator for any lubricant which may be contained therein, therebyfacilitating lubrication of said axle, even though but a small quantity of lubricant may remain within the outer end of the wheel hub. When it is desired to supply fresh lubricant tothe hub the cap may be removed, filled with lubricant, placed in position, and screwed home to the position shown in Fig. 2, whereupon more or less of the lubricant placed in said cup will be forced through the opening between the washer 22 and the axle and into the roller bearing chamber. When it is desired to remove the wheel from the axle, the lubricant cup is retracted, the plug 30 is removed, and the linch pin 32 may be removed through the opening in which said plug is seated. In the modification shown in Fig. 3. the flange 27 of the cup is provided with an annular ring 27 which rests between the plug 30 and washer 22, while the annulus 19 is in alinement with, but isnot inclosed' by, flanges from the cylindrical sleeve 16*. Otherwise the construction is the same as in the other figures.

What lt claim is:

l. In combination in a mine car, a pedestal box having an enlarged open end, packing seated in said open end, a wheel having a hub portion rotatable in said open end, said wheel having an" axle bore'of a plurality of diameters one of which serves as a roller bearing chamber and one as a lubricant chamber, a washer in said lubricant chamber of larger diametersthanthe roller bearing chamber, an axle extended through said pedestal box and said roller bearing chamber and into but not through said lubricant chamber, a linch pin seated in said axle in said lubricant chamber and an adjustable cap adapted to contain lubricant and force the same into said hub and also to hold said washer in position.

2. In a car wheel, a cast hub portion including a roller bearing chamber and a lubricant chamber at the end thereof thereby forming a shoulder, a roller bearing in said bearing chamber, a washer in said lubricant chamber, and a closed cup having an inwardly disposed flange seated in said "lubricant chamber and being movable to force said washer against said shoulder, said washer thereupon holding said roller bearing in position.

3. In a car wheel, a cast hub portion including a, roller bearing chamber and a lubricant chamber at the end thereof thereby forming a shoulder, a roller bearing roller supporting annulus in said bearing chamber, a washer in said lubricant chamber, and a closed cup having an inwardly disposed flan e seated in said lubricant chamber and eing movable to force said washer a ainst said shoulder, said washer then holding said annulus in position.

4. In a car wheel, a cast hub portion ineluding a roller bearing chamber and a end, said hub having an axle bore of a plu I rality of diameters forming roller bearing and lubricant chambers, a washer in the lubricant chamber of greater diameter than the roller bearing chamber, an axle extended through said pedestal box and the roller bearing chamber and entering the lubricant chamber, a linch pin connected to said axle in the latter chamber and an adjustable cap adapted to contain and force lubricant into said hub and also to force said washer into position.

6. In combination, a wheel with a hub having a roller bearing chamber and a lubricant chamber of greater diameter forming a shoulder in the hub wall at contiguous ends of said chambers, an axle, a roller bearing in said bearing chamber, a washer of greater diameter than said hearing chamber in said lubricant chamber, and ancup closing a hub end capable of unretarded movement into the lubricant chamber to force said washer'against said shoulder to retain said roller bearing.

7. In combination, a wheel hub with an open end and having a bore with succeeding portions of increasing diameter and formmouse ing a shoulder inset from the 0 en hub end, washer against said shoulder to retain said 10 an axle extending through and nearly closroller bearing. ing the bore portion nearest the opposite In witness whereof I have hereunto set {:ub end, a-roller bealring in lan intefimediate my hand in the presence of two witnesses.
